Upgrading and transformation of ordinary gas furnaces
Thread Content
Ordinary gas furnaces burn coal blocks to produce semi-water gas, which consumes high energy and causes great pollution. Need help to upgrade? ? ? method: 1. The transformation using coal-water slurry technology costs more than 200 million. The investment is large and the cost is too high, so it has been rejected. 2. Is it possible to use space furnace technology to transform ordinary furnaces? ? ? Ordinary furnace pressure: 0.06MPA, temperature: 200-320, while the pressure of the space furnace: 2.8MPA, temperature: 》1000 degrees. If the majority of sea friends can provide modification methods, I am willing to cooperate with them and both parties will benefit. 3. The technology of using briquettes, coal rods and other briquettes has been used in this project, but the effect is relatively poor. The main reason is that the briquettes are easily pulverized when exposed to water vapor. Can any friends give me some advice? ? ?
Coal gasification technology reduces the cost of synthetic ammonia production to a certain extent, but it is not a fundamental change in the gasification method. At present, the more popular gasifier types are multi-nozzle opposed coal-water slurry gasifiers and space furnaces. The use of space furnaces is later than that of multi-nozzle opposed coal-water slurry gasifiers. Currently, only two in Linquan, Anhui and Puyang, Henan have been put into use, and their use time is very short, and they have not passed the long-term test. The investment in space furnaces is said to be one-third cheaper than other gasification methods, but the investment is also quite large. After the multi-nozzle opposed gasifier was used in the large chemical fertilizer project in Dezhou, it is now in normal use in many factories such as Lunan and Linggu. It is a relatively reliable furnace type. No matter which furnace type is chosen, it needs to be carefully investigated and compared, and a decision should be made based on the coal quality.
Friends upstairs, can you provide some more detailed information about coal-water slurry and space furnace technology for reference? ? ? ! ! ! Thanks! ! !
Can you post the analysis of its raw coal so that we can compare it?
500 million? I'm afraid the boss is having a hard time with this. 1T ammonia furnace earns 300-400 yuan more than an ordinary furnace, which is very cost-effective, but the cost is too high. Small chemical plants cannot afford this. It’s hard to convince your boss to take on a project.
